Backend / Cloud
Go services, distributed systems, cloud infrastructure, and API integrations. I develop automation that connects tools and reduces manual work.
Maciej Karczmarz
I build backend, cloud, and automation projects with business needs in mind: reliable processes, useful data, and controlled operating costs.
Profile
Technology shaped by business needs.
I study Computer Science at Rzeszów University of Technology, specializing in cybersecurity and cloud solutions. I develop projects in Go, Python, AWS, and Kubernetes, connecting technical decisions with process needs, operating costs, and technological risk.
3D / Technical Art
Production experience optimizing 3D assets for Unity. I bring the same attention to performance, resource limits, and technical requirements to backend and cloud projects.
IT / Business processes
I translate process needs into integrations and automation. In SmartOffer, I worked with a team on B2B quoting for a business client; in Gix, I develop data collection cost estimation with a FinOps focus.
Security / IT audit
I am interested in systems security, IT audit, and technological risk assessment. I want to understand how infrastructure, data flows, and technical decisions affect business continuity.
Skills / Stack
Go, cloud, automation, APIs, and 3D tools.
Go, Blender, UE5, Unity, Houdini, AWS, n8n, Gaea, Quixel, and Substance 3D Painter.

Selected Projects
Systems, automation, renderers, and simulations.
Each project starts with a practical need: preparing B2B quotes, monitoring market data, or processing spatial data. I show the technical constraints and how the solution supports the process.
Project / 01
Gix
Real-time currency monitoring system that aggregates data from exchange points to provide current market insight.
- Role
- Backend / cloud cost engineering
- Constraint
- Live exchange-rate data, hosting, and operating cost must stay controlled.
- Impact
- Combines distributed exchange-rate data collection with Kubernetes deployment and Datadog observability. A cost estimation module is in development to support FinOps decisions.
Project / 02
SmartOffer
Team competition project for AB Bechcicki: automation of B2B offers and cost estimates for the construction industry.
- Role
- Automation / RAG workflow engineering
- Constraint
- Text, voice, and attachment-based inquiries need to be matched with a catalogue of around 98,000 products.
- Impact
- Combines AI search, n8n business workflows, and an AWS deployment to support preparing offers for a business client.
Project / 03
Nequ3D
An analytics platform processing reality capture data into OpenUSD scenes using NVIDIA RTX Neural Texture Compression.
- Role
- OpenUSD Edge-to-Core Pipeline
- Constraint
- Spatial scanning data (LiDAR) processing requires memory optimization, a high-performance backend, and offline analytical tools.
- Impact
- Demonstrates 3D systems architecture: Go backend, OpenUSD/Python processing, Wails analytics, and local LLM assistance for reporting.
Project / 04
Oentike
Local mushroom-conditions helper for Polish forests: explainable scores, a coarse seasonal map, and an offline atlas.
- Role
- Full-Stack Development
- Constraint
- Building a reliable local condition scoring system with an offline-ready atlas and precise geolocation data processing.
- Impact
- Delivers explainable condition scores and a 9-day season trend using Go, PostGIS, and an Astro UI with a Tauri desktop wrapper.
Project / 05
Honeypot
A Raspberry Pi honeypot stack collecting and visualizing attacks against exposed services for controlled academic scenarios.
- Role
- Security / Operations
- Constraint
- Needs a controlled, safe environment to track, ingest, and analyze cyber attacks against common protocols and fake web pages.
- Impact
- Integrates Cowrie, OpenCanary, Promtail, Loki, and Grafana into a cohesive pipeline for threat intelligence and log aggregation.
Project / 06
Sand-Simulation
Granular physics simulation focused on natural particle behavior and environmental interactions.
- Role
- Simulation / performance thinking
- Constraint
- A high number of particles needs simple, stable rules and efficient behavior updates.
- Impact
- Shows simulation thinking, compute efficiency, and believable behavior under motion.
Project / 07
GRATS
Minimal graphics renderer built to explore OpenGL and graphics programming fundamentals.
- Role
- Low-level graphics programming
- Constraint
- A renderer requires understanding the graphics pipeline closer to hardware and API behavior, not only finished engines.
- Impact
- Strengthens technical rendering knowledge that informs later asset, scene, and real-time performance decisions.
Project / 08
GRAT
Interactive weather data visualization system integrating OpenWeatherMap, Google Maps, and Windy into one readable application.
- Role
- Application / API integration
- Constraint
- Environmental data from several sources has to become consistent and readable.
- Impact
- Shows API integration, data visualization, location context, and desktop-tool thinking.
